Isaiah 43:21

The tone of the address is now suddenly changed. The sudden leap from reproach to consolation was very significant. It gave them to understand, that no meritorious work of their own would come in between what Israel was and what it was to be, but that it was God's free grace which came to meet it. "But now thus saith Jehovah thy Creator, O Jacob, and thy Former, O Israel! Fear not, for I have redeemed thee; I have called thee by name, thou art mine. When thou goest through the water, I am with thee; and through rivers, they shall not drown thee: when thou goest into fire, thou shalt not be burned; and the flame shall not set thee on fire." The punishment has now lasted quite long enough; and, as ועתּה affirms, the love which has hitherto retreated behind the wrath returns to its own prerogatives again. He who created and formed Israel, by giving Abraham the son of the promise, and caused the seventy of Jacob's family to grow up into a nation in Egypt, He also will shelter and preserve it. He bids it be of good cheer; for their early history is a pledge of this. The perfects after כּי in Isa 43:1 stand out against the promising futures in Isa 43:2, as retrospective glances: the expression "I have redeemed thee" pointing back to Israel's redemption out of Egypt; "I have called thee by thy name" (lit. I have called with thy name, i.e., called it out), to its call to be the peculiar people of Jehovah, who therefore speaks of it in Isa 48:12 as "My called." This help of the God of Israel will also continue to arm it against the destructive power of the most hostile elements, and rescue it from the midst of the greatest dangers, from which there is apparently no escape (cf., Psa 66:12; Dan 3:17, Dan 3:27; and Ges. 103, 2).

The contents of this chapter are much the same with those of the foregoing chapter, looking at the release of the Jews out of their captivity, but looking through that, and beyond that, to the great work of man's redemption by Jesus Christ, and the grace of the gospel, which through him believers partake of. Here are, I. Precious promises made to God's people in their affliction, of his presence with them, for their support under it, and their deliverance out of it (Isa 43:1-7). II. A challenge to idols to vie with the omniscience and omnipotence of God (Isa 43:8-13). III. Encouragement given to the people of God to hope for their deliverance out of Babylon, from the consideration of what God did for their fathers when he brought them out of Egypt (Isa 43:14-21). IV. A method taken to prepare the people for their deliverance, by putting them in mind of their sins, by which they had provoked God to send them into captivity and continue them there, that they might repent and seek to God for pardoning mercy (Isa 43:22-28).

43:21 One purpose of redemption is to honor God through the praises of the redeemed (see 1 Pet 2:9).
